Based on EOWG 30 Oct input, added:

, including text displayed in the video."

under https://deploy-preview-126--wai-media-guide.netlify.app/media/av/#how-to-make-audio-and-video-accessible and under https://deploy-preview-126--wai-media-guide.netlify.app/media/av/av-content/#plan-description

Edit before the meeting had added to https://deploy-preview-126--wai-media-guide.netlify.app/media/av/description/#writing this paragraph:

Generally, all text in the video should be included in the main audio (integrated description) or in the separate description. For example, title text at the beginning of the video, links and e-mail addresses shown at the end, speakers’ names in text, and text in a presentation. The text does not have to be included verbatim (exactly word-for-word), yet all of the information conveyed by the text needs to be available in the main audio, in the separate description, or clearly with the video.
